ExceptionTranslationFilter – Access is denied (user is anonymous)

Problem

Log error message

DEBUG: org.springframework.security.web.access.ExceptionTranslationFilter - Access is denied (user is anonymous); redirecting to authentication entry point org.springframework.security.access.AccessDeniedException: Access is denied at org.springframework.security.access.vote.AffirmativeBased.decide(AffirmativeBased.java:83) at org.springframework.security.access.intercept.AbstractSecurityInterceptor.beforeInvocation(AbstractSecurityInterceptor.java:206) at ......

Solution

This issue occurs due to following reason

Incorrect order of element in spring security config file.
‘Permit all’ is not sufficient for anonymous users. Due to which we need to add role ‘ANONYMOUS’ for desired pages.

protected void configure(HttpSecurity httpSecurity) throws Exception { httpSecurity.requiresChannel().anyRequest().requiresSecure() // Configures url based authorization .and().authorizeRequests() // Anyone can access the urls .antMatchers("/auth/**", "/login", "/signup", "/forgotPassword").permitAll() // The rest of the our application is protected. .anyRequest().hasAnyRole("ANONYMOUS, USER") // Configures form login .and().formLogin().loginPage("/login").failureUrl("/login?error=bad_credentials") // Configures the logout function .......... .and().rememberMe().tokenValiditySeconds(1209600).and().exceptionHandling().accessDeniedHandler(accessDeniedHandler()); }

Solution

Changed dataype of ajax.

$.ajax({ url : '/FileUpload/singleSave', type : 'POST', data : data, cache : false, dataType : 'json', // The type of data that you're expecting back from the server. processData : false, // Don't process the files contentType : false, // Set content type to false as jQuery will tell the server its a query string request xhrFields : { onprogress : function(e) {

Modified to

dataType : ‘text’, // The type of data that you’re expecting back from the server.

Solution

invalid target release: 1.7 indicates that the project is pointed to java 1.7 but maven is not.
Make sure maven is also pointed to correct jdk.

In my case, Java was pointing to jdk 1.7 but maven wasn’t.

java -version
java version “1.7.0_45”
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

$ mvn –version
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 08:22:22-0700)
Maven home: /……/apache-maven-3.1.1
Java version: 1.6.0_65, vendor: Apple Inc.
Java home: /…./1.6.0.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: “mac os x”, version: “10.9.5”, arch: “x86_64”, family: “mac”

Update maven configuration to point to java 1.7 to resolve this issue.
